In *nix, he child process inherits the nice value of the parent process, and, unless the process owner is the super-user, the child process cannot be given a higher priority. This would also apply to calls to system() and backticks, since they all basically use the same mechanism. It also applies to exec(), though that is a separate OS operation. Just out of curiosity, how is this handled in windows? Thanx, SmiddyThread Previous | Thread Next
